Progressive stamping
Progressive stamping for stator and rotor lamination is a stamping method that punches the strip material (cold-rolled electrical steel) in several stages before finally outputting the desired shape of stator/rotor lamination. Progressive stamping requires an automatic feeding system.
The feeding system pushes the strip through all stages of a progressive stamping die.
The final stage is a cutoff or output operation that separates the finished stator or rotor from the rest of the strip.
Progressive stamping for stator and rotor may be applied to loose sheets or auto-stacked motor core.
Stamping controller is required for auto-stacked motor core for defining number of strokes, shaft hole size selection and skewing/indexing parameters.
Progressive stamping dies are much more higher in price than compound dies. When production volume required is high, progressive stamping is preferred over compound stamping because it will save labor costs.
